2010 MatricesData represent abundance matrices with columns representing species or morphospecies of adult beetles found on baits of mature, fresh sporocarps of _Pleurotus ostreatus_ mushrooms. Each entry represents the number of individuals of that beetle species found on a particular bait type (see paper for experimental design of bait arrays). Rows represent individual mushroom baits, with letter codes corresponding to positions in experimental arrays as described in the manuscript. Each tab in the data file represents a different census. Adult beetles were censused mornings and evenings on consecutive days.2010_Matrices for Dryad.xlsx2011 MatricesData represent abundance matrices with columns representing species or morphospecies of adult beetles found on baits of mature, fresh sporocarps of _Pleurotus ostreatus_ mushrooms.

Ecological networks are useful for characterizing interspecific associations and predicting the resilience of ecological communities. We evaluated how such networks vary with the size, spatial distribution, and timing of availability of resources, with a focus on beetle-macrofungal associations. We used 2 y of field experiments to construct ecological networks based on manipulated sporocarp baits (resources; Pleurotus ostreatus) and natural communities of beetles (consumers) in a temperate forest. Centrality and interaction strength increased with resource size, but were associated weakly with resource density and isolation, and not at all with position within patches. Whole-network connectance was greater in mornings (when beetle richness and abundance were high) than evenings. Interannual differences in networks were consistent with differences in beetle communities between years. The capacity of networks to vary temporally, spatially, and as a function of resource traits is examined in light of understanding beetle-macrofungal associations, which are important components of fungal ecology.
